Abstract

Due to its numerous and major industrial uses, graphite is one of the significant carbon allotropes. Refractories and batteries are only a couple of the many uses for graphite. A growing market wants high-purity graphite with big flakes. Since there are fewer naturally occurring high-grade graphite ores, low-grade ores must be processed to increase their value to meet the rising demand, which is predicted to increase by >700% by 2025 due to the adoption of electric vehicles. Since graphite is inherently hydrophobic, flotation is frequently used to beneficiate low-grade ores. The pretreatment process, both conventional and unconventional; liberation/grinding methods; flotation methods like mechanical froth flotation, column flotation, ultrasound-assisted flotation, and electroflotation; and more emphasis on various flotation reagents are all covered in this review of beneficiation techniques. This review also focuses on the different types of flotation reagents that are used to separate graphite, such as conventional reagents and possible nonconventional environmentally friendly reagents.

石墨选矿用浮选技术及试剂综述

由于其众多和主要的工业用途，石墨是重要的碳同素异形体之一。耐火材料和电池只是石墨众多用途中的两个。不断增长的市场需要高纯度的大薄片石墨。由于天然存在的高品位石墨矿石较少，因此必须对低品位的矿石进行加工以增加其价值，以满足不断增长的需求，预计到2025年，由于电动汽车的采用，这一需求将增加500%。由于石墨本身疏水，浮选常用于低品位矿石的选矿。预处理工艺，包括常规和非常规;解放/研磨方法;机械泡沫浮选、柱浮选、超声辅助浮选、电浮选等浮选方法;本文对选矿技术进行了综述，重点介绍了各种浮选药剂。本文还重点介绍了用于分离石墨的不同类型的浮选剂，如常规浮选剂和可能的非常规环保浮选剂。

期刊介绍： International Journal of Chemical Engineering publishes papers on technologies for the production, processing, transportation, and use of chemicals on a large scale. Studies typically relate to processes within chemical and energy industries, especially for production of food, pharmaceuticals, fuels, and chemical feedstocks. Topics of investigation cover plant design and operation, process design and analysis, control and reaction engineering, as well as hazard mitigation and safety measures. As well as original research, International Journal of Chemical Engineering also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
